Forecast discussion: I hope everyone enjoyed their Thanksgiving, although we still had passing snow showers through the early evening and overnight on Black Friday morning. Here in Boston, snow showers during the early morning gave everyone from a coating to as much as 2 inches. Eventually, we had some sunshine by the early afternoon.
At this time, we have a strong high pressure system between Virginia and North Carolina. Despite the high, there is a very weak disturbance passing through the area, giving parts of south central Massachusetts an occasional flurry or two. As we move into this evening, skies will clear, and with calm winds temperatures will fall rapidly into the upper teens to near 20 degrees. Winds will begin to turn to the southwest by tomorrow night and see increasing clouds from a warm front. The extra cloud cover will give us a milder overnight temperature, as we will remain around freezing heading into Sunday.
As the front pushes through, we may see some isolated snow showers, but temperatures will increase through the early morning, turning to rain showers. I’m predicting temperatures will reach near 50 degrees on Sunday, and will continue into Monday. But, the warm front would have pushed into Canada, and temperatures will begin to fall. Colder air from a high pressure system from our northwest will lower our temperatures back below freezing Monday night.
A weak cold front will be reaching us by late Tuesday night. Some warmer air ahead of the low will bring our temperatures back into the upper 40’s on Wednesday. We should see rain showers early Wednesday morning, with a brief lull early Thursday morning. Temperatures will reach the upper 40’s on Thursday, but once again colder air will push back into Southern New England. The precipitation may become a rain/snow mix by Thursday night into next Friday morning.
